Figure 12From: Fourth-order compact finite difference method for solving two-dimensional convection–diffusion equationComparison figures of errors between the standard difference scheme and the compact difference scheme in Example 3. (a) Absolute error when \(T = 1, N = 32\) and \(K= N^{2}\). (b) Approximation order of C in \(L^{2}\)-normBack to article page
